InnoDC is a European Training Network (ETN) funded by the European Union's Horizon 2020 Marie Skłodowska-Curie Actions programme. ETNs provide training through doctoral research to talented early stage researchers (ESRs). InnoDC ESRs will enrol on PhD degree programmes and be employed for 36 months in a network of universities and industry with expertise in offshore wind power generation and supply. Through 15 ESR research projects, InnoDC will address the technical challenges linked to the development of offshore grids and hybrid AC/DC systems. Four of them will conduct the doctorate in the UPC. Further information on the overall project can be found at

This is a unique opportunity to study for a doctoral degree in a network of wind power and power systems experts from academia and industry. We are therefore looking for high qualified and motivated candidates with the skills, background knowledge and enthusiasm to help the network make important research breakthroughs.

Tools for analysis of novel concepts of transmission systems for offshore wind power plants

The need to reduce the cost of the offshore converter station has motivated the proposal of several pairs of combination of transmission system and offshore grid:

  • VSC-HVDC transmission + AC offshore grid at standard frequency. Possibility of using higher voltage at the collection grid (66 kV)

  • VSC-HVDC transmission + AC offshore grid at non-standard frequency

  • VSC-HVDC transmission + AC offshore grid at variable frequency with wind turbines of more reduced power electronics

  • VSC-HVDC transmission + DC collection grid using DC-DC converters

  • VSC-HVDC transmission + DC collection connecting the wind turbines in series

  • HVDC transmission using diode rectifiers or thyristors in the offshore converter stations + AC offshore grid controlled by the wind turbines

  • AC low frequency transmission + AC low frequency collection grid

The present project aims at studying the previous plus some additional concepts in order to develop a tool to allow a fair comparison both technical and economical. The comparison will include aspects related to the technology, efficiency, reliability, maintainability and availability of the different components and systems. Different scenarios will be studied and compared.
